A 1,1′-bitriphenylene-based silahelicene was synthesized with a high ee value by enantioselective double [2+2+2] cycloaddition of a biaryl-linked tetrayne with a silicon-linked bis(propargylic alcohol) as a key step. This silahelicene exhibited a high tolerance toward racemization, which could be explained by the X-ray crystal structure analysis. With respect to the photophysical properties, this silahelicene exhibited a relatively high fluorescence quantum yield and circularly polarized luminescence activity.
